Besides a few job posts Apple never formally admitted to being the occupant at 90 Hills Road in Cambridge. This week, however, Cambridge News has spotted confirmation of Apple’s presence in the city, in the form of the Apple logo appearing on signage outside of the office building.

For the last two years Apple has been tight-lipped about its office in Cambridge, but now it seems the iPhone maker is ready to come out of the closet.

The tech giant has repeatedly refused to confirm it is operating out of 90 Hills Road, next to the entrance of the Botanic Gardens. But now its iconic logo has appeared on signage outside the building.

Now, it is believed that more than 30 employees — including former staff from VocalIQ — are at work at the Cambridge office. Today’s report states that the workers at 90 Hills Road are “developing new versions of Siri to compete with the likes of Amazon and Google.” Last month, industry sources stated that Apple is working on “enhanced Siri” capabilities for future iPhones, citing another Apple acquisition (machine learning startup Turi), while also mentioning the company’s desire to best its competitors in the AI assistant space.
